Definitions

  • the following description relates to a method and apparatus for displaying driving information, and more particularly, to a method and apparatus for displaying road information by matching road speed information with a palette image on a point-to-point basis, and changing a color of a road image of a link identification (ID) into a predetermined color on the basis of speed information of the link ID extracted from received traffic information.
  • ID link identification
  • a transport protocol expert group is a standard for displaying traffic and travel information by a navigator having, for example, a built-in digital multimedia broadcasting (DMB) receiver, using i.e., a DMB broadcasting network.
  • DMB digital multimedia broadcasting
  • a navigator that provides a TPEG service performs intelligent road guidance based on road and traffic information received in real time over, for example, a terrestrial DMB channel.
  • the TPEG service navigator may display a road condition by color such as ‘blue’ for good condition, ‘orange’ for delay, ‘red’ for congestion and the like, on a navigation map.
  • the TPEG service navigator may inform a driver with the expected traffic circumstances such as traffic speed of a road, allow the driver to make a detour to avoid, for example, a blocked road, and guide the driver with the shortest distance course to a final destination.
  • the TPEG service navigator may provide information such as dangerous area/road condition information, accident information, restaurant information, trip information and the like.
  • a method for displaying a blocked road by color by a navigator having a TPEG service includes making and coloring a polygonal road shape.
  • this method may require a storage space for a coordinate value database, and by requiring a coordinate value for a road shape, processing speed may slow and coloring for a road type with a link ID cut may become difficult.
  • Another method includes coloring using a flood fill algorithm.
  • the flood fill algorithm is also referred to as a seed fill algorithm and is an algorithm for determining a portion connecting with a specified position in a multiple-dimensional arrangement.
  • the flood fill algorithm may be performed in such a manner that a target color changes into an alternative color following all nodes of an arrangement connecting with a start node. Because the flood fill algorithm may inevitably require a seed coordinate, there is a difficulty in implementing coloring for a road type with a link ID cut. Moreover, the flood fill algorithm may result in slower processing speed.
  • a method for an apparatus to display road information including receiving by the apparatus traffic information, and processing by the apparatus to display an image region corresponding to a link identification (ID) by a palette color corresponding to the traffic information on the basis of the received traffic information.
  • ID link identification
  • the processing to display may include extracting speed information corresponding to the link ID from the received traffic information, selecting a palette color matched to the extracted speed information, and changing a color of the image region into the selected palette color.
  • the method may further include storing the link ID and the selected palette color in a storage unit of the apparatus.
  • the traffic information may be received in real time.
  • the received traffic information may be transport protocol expert group (TPEG) data based on a TPEG protocol.
  • TPEG transport protocol expert group
  • an apparatus to display road information including a receiver to receive traffic information, a speed information extractor to extract speed information of a link identification (ID) from the received traffic information, a palette color selector to select a palette color matched to the extracted speed information, and a display unit to change a color of an image region corresponding to the link ID into the selected palette color and to display the image region.
  • a receiver to receive traffic information
  • a speed information extractor to extract speed information of a link identification (ID) from the received traffic information
  • a palette color selector to select a palette color matched to the extracted speed information
  • a display unit to change a color of an image region corresponding to the link ID into the selected palette color and to display the image region.
  • the apparatus may further include a storage unit to store the link ID and the selected palette color for the link ID.
  • the traffic information may be received in real time.
  • the received traffic information may be TPEG data based on a TPEG protocol.
  • the apparatus may be a navigation unit to provide driving information.
  • the link ID may correspond to a region having a starting point and an ending point, and the speed information may correspond to an average driving speed of the region.
  • FIG. 1 is a block diagram illustrating a construction of an apparatus to display road information according to an exemplary embodiment.
  • FIG. 2 is a diagram illustrating link identifications (IDs) around a river and a structure of a database therefor according to an exemplary embodiment.
  • FIG. 3 is a flow diagram illustrating a method for displaying road information according to an exemplary embodiment.
  • FIG. 1 illustrates a construction of an apparatus 100 to display road information according to an exemplary embodiment.
  • the apparatus 100 includes a transport protocol expert group (TPEG) receiver 110 including an antenna 110 a, a speed information extractor 120 , a palette color selector 130 , a display unit 140 , and a storage unit 150 .
  • TPEG transport protocol expert group
  • the TPEG receiver 110 receives traffic information from an external source through the antenna 110 a.
  • the received traffic information is forwarded to the speed information extractor 120 .
  • the traffic information is, for example, TPEG data based on a TPEG protocol.
  • the traffic information includes a link identification (ID) and traffic information ID including speed information (e.g., an average car speed) of the link ID.
  • the speed information extractor 120 extracts a link ID and speed information by link ID from the traffic information forwarded from the TPEG receiver 110 .
  • the speed information extracted by link ID is forwarded to the palette color selector 130 .
  • the palette color selector 130 selects a palette color that corresponds to the speed information forwarded from the speed information extractor 120 . For example, where the extracted link ID is equal to ‘10005’ and the speed information is equal to ‘300001’, a palette color of a region corresponding to the link ID is changed into ‘orange,’ thus illustrating that there is a delay or congestion. This is only exemplary and it is understood that palette colors may be selected to reflect a variety of road circumstances. The selected palette color is forwarded to the display unit 140 .
  • the display unit 140 changes a color of a displayed image region corresponding to the link ID into a palette color forwarded from the palette color selector 130 , and displays the image region.
  • the storage unit 150 stores the link ID and the palette color selected for the link ID.
  • FIG. 2 illustrates link IDs around a river, for example, a portion of the Han river near Seoul, Republic of Korea, and a structure of a database 220 therefor according to an exemplary embodiment.
  • a start point is the northern end of the Gayang bridge and an end point is the northern end of the Haengju bridge.
  • Link IDs and palette indexes representing palette colors may be matched with each other on a point-to-point basis in the storage unit 150 .
  • the palette index is constructed to have a different value depending on speed information extracted from received traffic information. Accordingly, a color of an image region of a road corresponding to the link ID ‘1001’ from the northern end of the Gayang bridge to the northern end of the Haengju bridge may be changed by changing the palette index representing the palette color. And the result may be displayed in a display 210 .
  • FIG. 3 illustrates a method for displaying road information according to an exemplary embodiment.
  • the TPEG receiver 110 receives traffic information from an external source through the antenna 110 a.
  • the received traffic information is forwarded to the speed information extractor 120 .
  • the speed information extractor 120 extracts a link ID and speed information corresponding to the link ID from the traffic information forwarded from the TPEG receiver 110 .
  • the extracted speed information is forwarded to the palette color selector 130 .
  • the palette color selector 130 selects a palette color that is matched, for example, on a point-to-point basis to the speed information.
  • the display unit 140 changes a color of a displayed image region corresponding to the link ID into a palette color forwarded from the palette color selector 130 and displays the image region.
  • the storage unit 150 stores the link ID and the palette color selected for the link ID.
  • the methods described above may be recorded, stored, or fixed in one or more computer-readable media that includes program instructions to be implemented by a computer to cause a processor to execute or perform the program instructions.
  • the media may also include, alone or in combination with the program instructions, data files, data structures, and the like.
  • Examples of computer-readable media include magnetic media, such as hard disks, floppy disks, and magnetic tape; optical media such as CD ROM disks and DVDs; magneto-optical media, such as optical disks; and hardware devices that are specially configured to store and perform program instructions, such as read-only memory (ROM), random access memory (RAM), flash memory, and the like.
